UNITED STATES PATENTS 1,367,639 2/1921 Tiffany 242/1 18.32 6 Claims, 2Drawing Figures PATENTED JUL30 I974 IN VENTOR. CLemenE D. LeHar'oly BY4M ATTORNEY' YARN TUBE This invention relates generally to yarn carriersand, more particularly, to draw twister tubes for storage andtransportation of textile yarn.

In the production of yarn, especially during the processing known asdraw twisting, it is necessary that yarn carriers or tubes have givensurface characteristics such, for'example, as those permitting smoothdelivery of the yarn at the point of use. The smoothness of the surfacenecessarily creates the disadvantage of the potential sliding orslipping of the yarn package from the tube. In an attempt to avoid theslipping, the tubular structures having surface characteristics such asribbed or creped parchment set forth in US. Pat. Nos. 3,362,655 and3,544,034, respectively, were developed. However, these constructionshave undesirable features in that there are breaks and sharp cornerscaused by 9the ribbing or creping which damage the yarn and preventproper delivery, especially of the primary winds close to the surface ofthe carrier.

It is an object of the instant invention to provide a yarn carrier whichwill have smooth delivery characteristics and a sufficiently roughenedsurface to provide proper delivery of yarn from the carrier.

A further object of the instant invention is to provide a yarn carrierwherein a penultimate ply of embossed material is covered by an ultimateply of smooth mate rial.

Still another object of this invention is to provide a base tube uponwhich an embossed paper is applied as the penultimate ply and having anouter ply of smooth, low pointage, parchment-type paper.

The above advantages of the instant invention will become more apparentwith reference to the following description when taken in conjunctionwith the attached drawings wherein like numerals refer to like elementsand:

FIG. 1 is a diagrammatic perspective view of a portion of a yarn carrierof the instant invention; and

FIG. 2 is a diagrammatic top view of a machine showing a method ofproduction of the tube of the instant invention.

Referring now to FIG. 1 wherein yarn carrier 10 is shown to include basetube 12 which may be of any number of plies of material. Generally basetube 12 would be constructed of fibrous material such as paper ofsubstantial strength and sufficient for retention of the crushing forcesof the yarn which is applied thereto. A penultimate ply of embossedmaterial 14 is wrapped around base tube 12. It is to be understood thatply 14 may be made of paper, such as low-mark cone paper, wovenmaterial, cloth, or an embossed paper having crests and troughs or highand low portions of somedesirable configuration. It is not necessarythat the depressions or raised portions have any given designs or area.However, it is anticipated that a reasonable degree and size should beanticipated.

The ultimate or outer ply 16 on carrier 10 is generally of a smooth,pliable, low pointage, parchment or parchment-type paper. However, it isto be understood that ply 16 could be of a film such as polyethylene orany given type of woven or non-woven material having relatively smoothsurface characteristics.

FIG. 2 shows a conventional spiral machine 20 in substantiallydiagrammatic form wherein drive belt 22 is shown passing over driverollers 24 and wrapped 2 about mandrel 26. Spiral machine 20 is ofconventional construction.

Base tube 12 is made by application of plies 21, 23 and 25. Althoughbase tube 12 is shown in FIG. 2 as comprised of three base plies, it isto be understood that any number of plies may be utilized which wouldgenerally be wound as shown in FIG. 2 utilizing a conventional adhesive.Ply 14 of embossed paper is applied to base tube 12 with conventionaladhesives. It is to be understood that, depending upon the undulationand degree of depression and length of span from rise to rise of thematerial in ply l4, rollers may be utilized to insure uniform and properthickness of ply 14. It is also possible to utilize rollers 30 forembossing or application of the ridges and valleys immediately prior tothe application of ply 14 to base tube 12. In this regard it is to benoted that the application of adhesive may be before, at or. after therollers 30.

Parchment or smooth ply 16 is generally applied beyond belt 22 in theconfiguration shown in FIG. 2. However, it is understood that ply 16 maybe applied prior to belt 22 in order to utilize the pressure of belt 22which wraps about the completed tube in insuring proper adhesion of ply16 to ply 14. In some constructions it may be advisable to apply ply 14beyond the belt. Depending upon the surface characteristics desired, italso may be advisable to utilize a softening process, such as wetting orother treatment in order to provide the desired characteristic to thecompleted tube.

Thus it is seen that the instant yarn carrier 10 provides a smooth, softsurface which has depressions and ridges which will permit properdelivery of a yarn and prevent slipping of the yarn from the carrier. Itis also observed that any given surface characteristic may be utilizedby appropriate selection of outer ply 16. The degree of undulation orsurface configuration will depend to a large extent upon the type ofembossing or marking of penultimate ply 14. It is to be understood thatappropriate selection of thematerials from which ply 14 is made maypermit an effect upon the winding of yarn on carrier 10. For example, asoft material will compress at the ridges in response to theconstrictive forces of the yarn to increase yarn slip resistance. Outerply 16 may be treated in order that when wound on the tube the thinsheet will be permitted to shrink onto the surface of the tube andthereby conform more to the configuration of the markings on the ply towhich it is adhered. It has been found that wetting a parchment ply 16causes the parchment to stretch tighter from ridge to ridge and therebyspan the depressions'more than in other constructions and therebyprovide a smooth surface capable of compression of differing amounts tohold the yarn on the carrier.

What is claimed is:

l. A yarn carrier comprising a base tube; a penultimate ply of embossedmaterial having ridges and depressions; and an outer ply of thin, smoothand pliable material which generally follows the countour of theembossed ply and having portions spaced therefrom, whereby a yarncarrier is provided having an undulating surface that precludes slippingof the yarn package while allowing proper yarn delivery.

2. A ya'rn carrier comprising a base tube; a penultimate ply of embossedmaterial having ridges and depressions; and an outer ply of thin, smoothmaterial 5. The method of claim 3 including the step of treating saidouter ply just prior to application thereof to said embossed ply.

6. The method of claim 3 including the step of passing said embossed plythrough leveling means just prior to application thereof to said basetube, whereby said embossed ply is of a substantially constant thicknessbetween the tops of the embossing and the opposite surface of said ply.
